Shared volume is disconnecting nightly

Beginning three days ago (with no changes to the server) a single user on our network has been greeted each morning with a dialog reporting that the main shared volume on our 10.5.8 server has been disconnected. "Server connections interrupted. Ignore. Disconnect All." Choosing any option results in the server volume staying mounted but the files are unavailable (spinning gear forever when browsing the mounted volume). Only restarting the client and remounting the shared volume fixes the problem.

The other user on our network sees no such message, though this Mac is set to go to sleep during the night whereas the one receiving the message does not sleep.

Both clients are running the latest version of Lion.

I'm not sure where to begin diagnosing this. Is it likely a server issue or a client issue? The behavior points to a client problem. What logs should I examine to get a clue?

I appreciate any suggestions.

Thanks!

Any ideas?

Any ideas why a single computer on the network would be greeted every morning with a "Server connection interrupted. Ignore. Disconnect All" dialog?

And whether the user clicks Ignore or Disconnect All, the mounted volume stays mounted but shows the spinning gear forever when browsing. The only fix is rebooting the client.

Anything?

Possibly CronoSync?

Now that I ponder it, I did update CronoSync on the client last week and CS is set to automatically back up certain client data files to the server volume each night.

I wonder if CronoSync is somehow causing the issue?

Exactly what logs should I be examining in the console? I note that CronoSync has not written any logs. There's a heading for it, but no logs underneath.

Still looking at the logs.

One thing that's jumping out is that this is appearing a ton of times:


com.apple.launchd.peruser.501[161] (com.akamai.client.plist[19741]): Bug: launchd_core_logic.c:4753 (25693):13

here are some entries discussing chronosync:

ChronoAgentLocal[19693]: ChronoAgentLocal v1.3.3 Init.

Thanks. I'll take care of that.

(Curse Adobe for all their bloatware...)

Meanwhile, I've disabled Chronometer's nightly scripts to see if that's the problem.
